Non-ideal achromatic flat lenses for a large-scale diameter up to 10 mm were experimentally realized and reported recently, which demonstrated a broad working bandwidth from 400 to 1100 nm.
Three-dimensional photoacoustic tomography synchronized with an electrocardiogram provides highly resolved images of a beating heart with optical absorption contrast and enables investigation of cardiovascular diseases in animal models.
A BP/CdS heterostructure-based artificial photonic synapse with an ultra-low power consumption is proposed, presenting great potential in high-performance neuromorphic vision systems.
Tip-molecule interactions and molecular motions such as molecular tilting and hopping process were explored via sub-nanometer-resolved tip-enhanced Raman Spectroscopy with single-chemical-bond limit.
